BWR internals Ni-based alloy welds Phased array Ultrasonic testing
As nuclear power plants age, the importance of maintenance increases and there is a need to apply inspection technologies suitable to importance of each item of equipment. In boiling water reactors, advanced inspection technologies are expected for internal components, i.e. shroud supports with complex-shaped Ni-based alloy welds. As an inspection technology for field inspection of the shroud supports phased array technology has been mainly developed for sizing of Stress Corrosion Crackings accessed from ...

Laser-ultrasonics Penetrant Testing Preventive maintenance SAFT Weld Defect
Multifunction laser welding head has been developed. The head is able to perform not only underwater laser welding as repair, but also laser peening as preventive maintenance and laser ultrasonic test ing as inspection. For inspection with multifunction laser welding head, a new method of visualized weld defects in water by laser-ultrasonics has developed. To detect and visualize a surface of weld metal with welding bead, the authors have developed a new detection method by leaky wave induced by interactio...

Array Probe Eddy Current Testing Surface Inspection Technique
Abstract An eddy current testing (ECT) system has been developed for inspecting weld surfaces of components in the reactor pressure vessel of nuclear plants. The system can be applied to curved surfaces with an ECT array probe, it can discriminat e flaws from other signal factors by using a combination of arrayed coils signal-phase. The system is applied to a mock-up of core internal components and the signal discrimination using the signal-phase clearly separated flaw and noise signals....

Components in RPV Eddy Current Testing Flaw Length Sizing Flexible Probe
1 flexible multi-coil eddy current testing (ECT) probe and a method for measuring the length of flaws have meen developed for inspecting comple x structures in the reactor pressure vessel of nuclear plants. The probe can be applied to curved surfaces that are larger than a curvature rad ius of 20 mm. And we propose the nethod for measuring the flaw length by introducing a decibel drop method of the ECT output signal. From the te st results of various EDM notches using the probe and the measuring method, we...
